PUBG Mobile Account Locked in Security Mode Despite Repeated Login Attempts

Hello, I recently acquired a PUBG Mobile account from a friend and have been logging in via Facebook. However, my account was put into security mode, with a message indicating it would be accessible again on November 11. When I tried logging in on that date, I briefly accessed the account before it logged me out and displayed a new notification saying it would reopen on November 14. This repetitive delay is extremely frustrating. I don’t understand why this issue keeps happening, especially after waiting for the initial access date. I urgently request that this problem be resolved so I can fully access my account without further delays.
